The experiment was carried out during the spring and summer seasons of the year 2017-18 and 2018-19 at the Horticultural Research Farm, AAU, Anand to study the “Effect of soil and foliar applications of micronutrients on flowering and yield of mango variety”. The experimentcomprised of 13 treatments of different micronutrients application viz. FeSO4 100 g, ZnSO4 100 g, Borax 100 g and multimicronutrients grade-V 400 g as a soil application; FeSO4 0.5 %, ZnSO4 0.5 %, borax 0.2 % and multimicronutrients grade-IV 1.0 % as a foliar application and its combinassions and control (water spray). Soil application was done at second fortnight of September and foliar sprays of treatments were done at flower bud initiation, full bloom stage and pea stage initiationon 18 years old mango tree cv. Mallika. Experiment was laid out in a Completely Randomized Design (CRD) with three repetitions. Numbers of staminate, hermaphrodite and total number of flowers per panicle were found significant with respect to various micronutrients treatments during both the years of experiment. Maximum staminate flowers per panicle, hermaphrodite flowers per panicle and total number of flowers per panicle was found with soil application of multimicronutrients grade-V 400 g followed by foliar application of multimicronutrients grade-IV 1.0 % during both the years of study. The significantly higher number of fruits, average fruit weight and fruit yield per tree were recorded with soil application of multimicronutrients grade-V 400 g followed by foliar application of multimicronutrients grade-IV 1.0 % during the years 2017-18 and 2018-19.

The flowering induction in mango (Mangifera indica L.) orchards is an agricultural practice carried out on tropical regions to obtain fruits out-of-season looking to reach better sale prices. The objective of this research was to evaluate the effect of potassium (PN), ammonium nitrate (AN) and paclobutrazol (PBZ) on flowering induction and fruit production in mango cv. Tommy Atkins. The experiment included fourteen treatments with 2, 4, and 6 % PN, and 2, 3 and 4 % AN applied in combination with PBZ (1 g of a.i. m-1 of canopy diameter), paclobutrazol alone (1 g of a.i. m-1 of canopy diameter), and a control (water), which were arranged in a completely randomized design with three replicates. Results show that floral induction and fruit production were improved: PBZ followed by foliar application PN 2 %, 4 % or 6 % induced flowering 16 days after treatments. Likewise, the major number of emerged panicles were obtained with PBZ + PN 6 %. An increase on fruit weight and size reduction was observed at harvest. PBZ followed by foliar application of nitrates induced flowering and enhanced the number developed panicles in mango cv. Tommy Atkins.RESUMENLa inducción floral en mango (Mangifera indica L.) es una práctica agrícola común en regiones tropicales, tendiente a obtener frutos fuera de temporada para lograr mejores precios de la cosecha. Este trabajo tuvo como objetivo evaluar el efecto de tratamientos de nitrato de potasio (PN), nitrato de amonio (AN) y paclobutrazol (PBZ) sobre la inducción floral y producción de fruto en mango cv. Tommy Atkins. Los tratamientos con PN al 2, 4, y 6 % y AN al 2, 3 y 4 % fueron aplicados solos o combinados con PBZ (1 g de i.a. m-1 de diámetro de copa), PBZ solo y un testigo (agua) bajo un diseño completamente al azar, con tres repeticiones. Se midieron variables de inducción floral y producción de fruto. Los resultados muestran que aplicación foliar de PBZ seguida de PN (2 %), (4 %) o (6 %) indujeron floración 16 días después del tratamiento. El mayor número de panículas emergidas se obtuvieron con PBZ + PN 6 %. Se observó una reducción de peso y tamaño de fruto a la cosecha. El PBZ seguido de aplicaciones foliares con NP y AN induce floración y aumenta el número de panículas desarrolladas en mango cv. Tommy Atkins.

A field trial was conducted during 2015 and 2016, to study the effect ofgrowth regulators on growth, flowering, yield and fruit quality of strawberry cv. Chandler. The experiment was laid out in completely randomized design with 16 treatments viz.CPPU at 1, 2 and 4 ppm, GA3 at 25, 50 and 75 ppm, Promalin at 2, 4 and 6 ppm, GA4+7 at 5, 10 and15 ppm, NAA at 10, 20 and 30 ppm and control (water spray) and each treatment was replicated thrice. The results revealed that the plants sprayed with 15 ppm GA4+7 two weeks before flowering significantly reported highest plant height (33.43 cm), leaf area (239.70 cm2), number of flowers (31.94), fruit set (87.45 %), number of fruits per plant (29.02), yield (540.01 g/plant), fruit length (53.63 mm) and fruit diameter (37.19 mm) and fruit weight (23.70 g) as compared to control. This treatment resulted in 196.36 % increase in yield and 56.22 %in fruit weight over control. Plants sprayed with 6 ppm promalin also showed significant improvement in vegetative growth, fruit size, yield and fruit quality, which resulted in 137.92 % increase in yield and 51.81 % increase in fruit weight over control. Hence, it is concluded that foliar spray of 15 ppm GA4+7 applied 2 weeks before flowering is beneficial in improving growth, yield and fruit quality of strawberry plants.

Lowbush blueberries (Vaccinium angustifolium Ait.) in two commercial fields were treated with a preemergent soil application of ZnSO4 at 0.34 g Zn/m2 or a prune-year or crop-year foliar application of Zintrac (1.76 g Zn/L) in a RCB design with five treatments and nine blocks, using 1.5 x 15-m treatment plots. Prune-year foliar Zintrac treatments were applied 20 June and 30 June at 53.8 mL·m-2 or 20 June at 107.6 mL·m-2. A crop-year application of Zintrac at 53.8 mL·m-2 was made on 26 June at only one location. Composite leaf tissue samples taken 14 July of the prune year indicated that two applications of Zintrac at 53.8 mL·m-2 raised Zn concentrations at both locations more than a single application at twice the rate. Soil application of ZnSO4 did not raise leaf Zn concentrations compared to the control at either location. Crop-year leaf samples taken 6 July at the site that received the crop-year foliar treatment indicated no carryover effect of prune-year Zn treatments on leaf Zn concentration, but crop-year foliar application of Zn from Zintrac did raise leaf Zn concentrations compared to the controls. The characteristics of stems sampled in the fall of the prune year at each location (stem density, stem length, flower bud formation) were not meaningfully affected by any of the prune-year treatments. Blueberry yield was not affected by any of the treatments at either location. These data suggest that control plot leaf Zn concentrations of about 15 ppm in both fields were adequate. Raising the leaf Zn concentrations to about 80 ppm with two applications of Zintrac at 53.8 mL·m -2 had no effect on growth or yield.

N Rates

Nitrogen and micronutrients have a key role in many citrus plant enzyme reactions. Although enough micronutrients may be present in the soil, deficiency can develop due to soil depletion or the formation of insoluble compounds. The objectives of this study were to (1) determine the adsorption, distribution, and availability of Zn in a sandy soil; (2) compare the effectiveness of foliar and soil application methods of Zn on Huanglongbing [HLB] affected trees; (3) compare foliar application rates of Zn for HLB-affected trees; (4) determine the effect of N rates on yield, soil inorganic N distribution patterns, and tree growth parameters. Tree rows were supplied with three N rates of 168, 224 and 280 kg·N·ha−1 and Zn at single and double recommended rates (recommended rate = 5.6 kg·Zn·ha−1) using foliar and soil application methods, in a split-plot experimental design. The results show that Zn concentration in the 0–15 cm soil depth was three times higher than the 30–45 and 45–60 cm soil depths during the study. An adsorption study revealed high Zn (KD = 6.5) sorption coefficients at 0–15 cm soil depth, while 30–45 and 45–60 cm depths showed little sorption. Leaf Zn concentration for foliar spray was two times higher than the soil application method. A nitrogen level of 224 kg N ha−1 improved canopy volume when compared to other N levels at the expense of reduced fruit weight. Foliar Zn application at 5.6 or 11.2 kg ha−1 and N rate at 224 kg ha−1 appear to be adequate for improving the performance of HLB-affected citrus trees.

The effect of zinc sulfate and zinc chelate on the leaf mineral content, yield and fruit weight of the peach variety Andross was investigated in a Greek orchard. Foliar application of a 25% zinc sulfate solution on 25 February and 2% zinc chelate solution on 20 May increased the zinc content of leaves and no toxicity was observed. In contrast, foliar application of 6% zinc sulfate and soil application of zinc sulfate at a rate of 200 g/tree on 25 February did not affect the zinc content of leaves. However, zinc sulfate applied to the soil at a rate of 200 g/tree significantly increased fruit yield. Statistically, the mean fruit weight and the susceptibility of fruit to Monilinia laxa did not differ between treatments. However, postharvest fruit susceptibility to M. laxa increased when fruit were dipped in a zinc chelate solution.

The present study was carried out during the seasons of 2014 and 2015 at the Research and Agricultural Experimental Station, King Saud University, Saudi Arabia, to investigate the effects of foliar application of CaCl2 at 1 or 2%, Ca(NO3)2 at 0.5 or 1% and ascorbic acid at 50 or 100 ppm on yield and fruit quality of Ziziphus jujuba trees. All treatments were repeated twice (December 15 and January 15) before harvest date in both seasons. Treatments significantly improved yield and fruit physical characteristics (fruit weight, flesh weight, fruit volume, fruit length, fruit diameter and fruit firmness) in comparison to untreated control in both seasons. Fruit chemical characteristics (TSS, Acidity, total sugar contents, ascorbic acid, and total chlorophyll) were mostly improved by most tested treatments in both seasons over the control (water only). It can be concluded that foliar application with Ca(NO3)2 at 1% would be the best treatment to obtain highest yield, fruit physical and chemical composition of Z. jujuba.

Field experiments were conducted during 1999-2000 and 2000-2001 to study the effect of basal application (BA) of zinc sulphate (5 and 10 mg kg-i soil) or boric acid (1 and 2 mg kg-1 soil) alone or foliar applications (FA) of water or 1% ZnSO4 or 1% H3 B03 or the combinations of both BA and FA of either ZnSO4 or H3 B03 on yield attributes (number of flowers and fruits/ plant, fruit weight, size and total yield). On the basis of the two-year data, it was found that all the treatments of BA as well as FA enhanced yield attributes but the combination of BA of 10 mg kg--1 soil ZnSO4 and FA of 1% H3 B03 gave highest yield as compared to other treatments and control plants.

The appearance of blossom-end rot (BER) in tomato is related to a decrease in the absorption and translocation of Ca due to excessive salinity in the soil solution. An experiment was conducted to investigate the effects of calcium nitrate (NT), EDTA-Ca (ED) and Aminoquelant-Ca (AQ)—a product containing Ca, B and protein hydrolisate—on the yield and incidence of BER when applied to the leaves of tomato (Lycopersicon esculentum Mill. `Durinta') grown in the open with a drip irrigation using saline water from a well (mean ECw 5.2 dS·m–1). The three calcium treatments and control were replicated four times, with 12 plants per replication, in a completely randomized design. Although yield per plant was higher with AQ, the difference was not statistically significant. Fewer fruit were affected by BER after treatment with ED and AQ than with NT and in the control. Leaf Ca concentration did not differ significantly between treatments. However, leaf B concentration was higher after treatment with AQ. Fruit Ca and B concentrations did not differ significantly in any treatment. The total free amino acids content in leaves was higher after AQ treatment than in the other treatments and control, although no significant difference was observed between the treatments in the fruit.
